Acts 17:10 And the brethren immediately sent away Paul and Silas by night unto Berea: who coming thither went into the synagogue of the Jews.11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. Here is a site giving scriptural references for the Nicene creed of 381 A.D. http://www.serfes.org/orthodox/holyscripturereferencestothecreed.htm Below is a line from the Nicene creed that is not really supported by scripture. "Who together with the Father and the Son is worshiped and glorified, ( Matthew 3:16-17 ) " Matthew 3:16 And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: 17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased. That reference is only about the Father & the Holy Spirit testifying that Jesus is God at Jesus's water baptism by John the Baptist. That is far far far away from validating the "practice of worshiping the Holy Spirit with the Father and the Son". We can find a lot of verses about how the Holy Spirit is God, but where is the instruction to practice worshiping the Holy Spirit with the Father and the Son? It's nowhere. And it is because God the Father told us how He wants us to come to Him in worship in honoring Him ( John 5:22-23 ) and that is by way of the Son ( John 14:6 ) Whom the Holy Spirit has been sent to lead us to testify of ( John 15:26-27 ) and to glorify ( John 16:13-14 ) even in worship ( Philippians 2:5-11 & John 13:31-32 ). Now if I missed a verse, feel free to correct that site for giving a wrong scriptural reference for the practice of worshiping the Holy Spirit with the Father & the Son, because Matthew 3:16-17 is not it. Galatians 4:16 Am I therefore become your enemy, because I tell you the truth?
